Booster Plug

Selling Booster Plug only done 1000 miles had a ECU flash so surplus to requirements, paid £120 asking for £75

Jeffro, why would you want a Booster plug - you are the one who says there is nothing wrong with the throttle!!

Yeh that's right as far as the snatchiness goes that everyone complains about! Pure throttle control of the wrist!
However, I am trying to sort out the "constant throttle" hunting and hesitation at low revs. Very different to the throttle problem everyone talks about!.
What do they say about people that assume?

I'm not sure what you mean by "02 is added" - talking about nitrous??

The hunting is caused by 2 things, depending upon how much throttle you have open
  • 02 Closed Loop
  • Switching maps

02 closed loop is used at very small throttle openings and the o2 sensor keeps adjusting the mixture to keep it very lean and clean, thus a booster plug will have no effect as it will be over ridden by the ECU, unless you also use a O2 sensor eliminator with the booster plug or reflash the ECU (but then the booster plug is pointless)

At about 10% throttle the ECU swaps between Pressure and Throttle position maps, if they are not exactly aligned at that point you will get the hunting feeling as it swaps back and forth between the maps - the booster plug may help this by making both of them richer and thus there is less difference.

At high throttle openings/high RPM the standard bike is too rich so it will just get richer still with the booster plug, losing power and using more fuel

Booster plug worked for me on the hunting etc. Its smoother off the fuel cut too - but it does not solve that one completely. £75 is a bargain if you, like me, had all the 'non-existent fueling issues'. Takes no time to fit. Does not feel rich on the throttle but who knows, maybe it does rob a bit of horsepower at the top - but I have not noticed. It made a heap of a difference in enjoying the ride and a long way short of cost vs.a reflash and remap.

im sure what your saying is what i read in booster plug website ....How it works long version....i believe i read the booster with o2 sensor does not add gas at constant throttle,,it keeps the stock lean setting for better gas mileage ...once throttle is moved the extra fuel is added........with o2 eliminator and booster extra fuel is added even at constant throttle...................now with no booster and just o2 eliminator at constant throttle it doesnt run of the lean gas saving stock map..it runs of the stock richer map as if you where opening the throttle.....maybe not worded correctly but am i in the ball park with my understand......thanks
